We must consider that of desires some are natural, others vain, and of the natural some are necessary and others merely natural; and of the necessary some are necessary for happiness, others for the repose of the body, and others for very life. Unhappiness comes either through fear or through vain and unbridled desire; but if a man curbs these, he can win for himself' the blessedness of understanding. Of desires, all that do not lead to a sense of pain, if they are not satisfied, are not necessary, but involve a craving which is easily dispelled, when the object is hard to procure or they seem likely to produce harm. Wherever in the case of desires which are natural, but do not lead to a sense of pain, if they are not fulfilled, the effort is intense, such pleasures are due to idle imagination, and it is not owing to their own nature that they fail to be dispelled, but owing to the empty imaginings of the man. The disturbance of the soul cannot be ended nor true joy created either by the possession of the greatest wealth or by honour and respect in the eyes of the mob or by anything else that is associated with causes of unlimited desires. We must not violate nature, but obey her; and we shah obey her if we fulfil the necessary desires and also the natural, if they bring no harm to us, but sternly reject the harmful. The man who follows nature and not vain opinions is independent in all things. For in reference to unlimited desires even the greatest wealth is not riches but poverty. Insofar as you are in difficulties, it is because you forget nature; for you create for yourself unlimited fears and desires. It is better for you to be free of fear lying upon a pallet, than to have a golden couch and a rich table and be full of trouble.

…… The alternative is a pick-and-mix social landscape. At the moment ethnic minorities are moving in different directions at different rates, with personal and social engagement across ethnic boundaries increasing all the time. One crude indicator is the level of mixed race marriage: one in five Bangladeshi and Pakistani men born in Britain now has a white wife, and one in five babies born in Britain has one Afro-Caribbean and one white parent. This implies a Britain in which people will construct multiple identities defined by all sorts of factors: class, ethnicity, gender, religion, profession, culture and economic position. It won't be clear-cut. Not all ethnic minorities, or members of an ethnic minority, will be moving in the same direction or identifying the same issues at the heart of their identities. It's about deciding who you are, but also about how other people define you. That's what will be at the heart of the next 50 years: enduring communities linked by blood through time versus flexible, constantly shifting identities. Identity won't be about where you have come from; it will be a set of values you can take anywhere that is compatible with full participation in whichever society you live in.
